Recent media reports tell alarming stories from the United States to Uzbekistan about volumes of missing radioactive materials, with headlines warning of the potential for terrorist attacks using these nuclear materials. It's no surprise then that understanding and learning how to deal with the real threat from Radiological Dispersal Devices (RDD), known commonly as "dirty bombs," is of top concern to the national security of countries around the world.
Canadian nuclear scientists are working on the battle frontlines of RDD research, determining how dirty bombs can be constructed and assessing associated risks. RDDs use conventional explosives, but are packed with nuclear materials, which when detonated can be dispersed over a wide area, and thus are considered particularly dangerous threats.
